How to boost immunity (with natural foods and remedies)

Causes of low immunity 

Some situations that can cause the weakening of the immune system are poor diet, poor hygiene habits, not being vaccinated when necessary, and smoking. In addition, during pregnancy it is normal for the immune system to fall, which occurs naturally in all women, as a way of preventing the mother’s body from rejecting the baby, and during treatment against cancer or the HIV virus.

People who have a syndrome or other illnesses like lupus or malnutrition also naturally have a less efficient defense system and become ill frequently. The use of certain medications, such as corticosteroids, immunosuppressants used in the case of organ transplants, during cancer treatment or with the prolonged use of some anti-inflammatory drugs, such as Dipyrone, also decrease the body’s immunity.

How to tell if your immune system is weak

The immune system is composed of the white portion of the blood, responsible for the production of antibodies whenever the organism is exposed to some foreign body, such as viruses or bacteria. However, the defense mechanism can also be considered to be composed of the skin itself and the acidic secretion of the stomach, which often neutralizes the microorganisms present in food, preventing them from developing inside the human body.

What characterizes a weakened immune system is the increase in the number of times that the person becomes ill, presenting flu, colds and other viral infections such as herpes, very often. In this case, it is likely that your body is not able to produce defense cells efficiently, which facilitates the onset of diseases. In this case, in addition to being routinely ill, the person may show symptoms such as tiredness, fever, and have simple diseases that worsen easily, such as a cold that turns into a respiratory infection, for example. See more  symptoms that indicate low immunity .
